Having been in enough relationships, this will probably end up backfiring, the way that all well-meaning gestures tend to.

How many people would want someone to post a picture of them with their names, plans etc out in the wild for this reason.

They may be young enough to be part of the new generation, that has a lot less expectation of privacy, and is a lot more comfortable with "oversharing" online.

The same way my generation is a lot more comfortable with openly displaying tattoos, and piercings, that previous generations weren't okay with.
